Re: [Bug] gspca_zc3xx v.2.14.0 Auto Gain is OFF

[Sam Bulka]

Just wanted to add, in previous driver version 2.13.0 Auto Gain was 
switchable ON / OFF, but when switched ON, was activated all the time 
regardless 
of lighting conditions, resulting in overexposed images during a day light with 
only silhouettes visible. But in current version its impossible to switch Auto 
Gain 
ON, or its default settings are wrong so it just doesn't work at all.

There are long term and current driver maintainers frequent here, pls fix the 
issue. :)

Hi Sam,

Thanks for the detailed bug report. Unfortunately I don't have time to look into
this atm. Perhaps someone else reading the list has time to look into this ?

Regards,

Hans
